How to Maintain Your Espresso Machine: Daily, Weekly, Monthly

Espresso machines are precision tools. Without regular cleaning, scale builds up in the boiler, old coffee oils clog the group heads, and milk residue ruins your steam wand’s performance. These issues don’t just degrade taste—they shorten machine life and increase repair costs. Whether you're a café owner or a home barista, keeping your machine in top shape is non-negotiable.

To properly maintain your espresso machine, clean the group heads daily, deep-clean with detergent weekly, descale the boiler monthly, and purge the steam wand after every use. Each task takes minutes but prevents major problems down the line.

Daily Espresso Machine Cleaning Routine

Start your day with a clean machine. Every espresso machine used for commercial or frequent home brewing requires these essential daily tasks to prevent buildup and ensure consistent extractions.

• Insert a backflush disc (also called a blind filter or rinse disc) into a double portafilter and lock it into the group head.
• Power off the machine.
• Hold down the 60ml brew button while turning the machine on. Keep holding until the screen displays 'cleaning', then release—the machine will run an automatic backflush cycle.
• Fill a 600ml milk pitcher with 300ml cold water and use it to purge and clean the steam wand. Heat the water to around 60°C during the process.
• Wipe down and clean the drip tray to remove coffee grounds and old liquid.

Weekly Deep Cleaning Steps

Once a week, go beyond the daily rinse. This involves using espresso machine cleaner to break down coffee oils and residues that build up over time, especially inside the group head and on the filter screens.

• Place a backflush disc into a double portafilter and add 2g of espresso machine cleaning powder (about half a short coffee spoon)—then lock it into the group head.
• Turn the machine off, then hold the 60ml brew button while powering on until ‘cleaning’ appears on the screen. Release the button and let the machine run its cleaning cycle.
• Again, purge the steam wand using 300ml of 60°C water in a 600ml pitcher.
• Use a short coffee spoon to carefully remove the group gasket and filter basket from each portafilter. Wipe the group head thoroughly with a clean cloth.
• Soak the removed filter baskets and portafilters in hot water mixed with 5g (one short spoon) of espresso machine cleaner.
• Clean the group gaskets and drip tray again, ensuring all rubber or silicone parts are free of residue—but do not soak any rubber or silicone components in the cleaning solution.

Monthly Boiler Maintenance

Your machine’s boiler needs attention monthly to prevent mineral scale buildup, which can affect heating efficiency and water flow. This step ensures your boiler stays in optimal condition.

• Open the machine’s drain valve to let water escape from the boiler.
• Locate the black switch beneath the electronic display panel. Turn it 180 degrees to the 'on' position (slow the adjustment if needed). Note: the switch is 90° when off and 180° when on.
• After draining the boiler completely, remember to turn the black switch back 90 degrees to the 'off' position.

How to Clean Your Grinder

The grinder is just as critical as the espresso machine. Old coffee oils and grounds inside the burrs and bean hopper can affect taste and performance. Here’s how to keep it fresh.

• Remove the bean hopper and empty any remaining coffee beans into an airtight container. Thoroughly wash and dry the hopper.
• Grind any leftover beans into powder to clear the burrs, then use a brush to sweep away all coffee dust and residue.

Frequently Asked Questions

How often should I backflush my espresso machine without cleaner?

You should backflush your espresso machine daily using just water and a blind filter (backflush disc) to clear old coffee oils from the group head. This takes just a minute and prevents buildup that affects taste and extraction.

Do I need to use espresso machine cleaning powder every week?

Yes. Using around 2g of espresso machine cleaning powder (roughly half a short coffee spoon) once a week during a backflush helps dissolve hardened coffee oils inside the group head and filter basket, maintaining extraction quality.

Can I soak rubber or silicone parts in the espresso machine cleaner?

No. Never soak gaskets, group head seals, or the drip tray in the cleaning solution. Only metal parts like filter baskets and portafilters should be soaked in the hot water and cleaner mix. Rubber and silicone degrade when exposed to detergent for extended periods.

What temperature should water be for steam wand cleaning?

Use water heated to around 60°C (not boiling) to purge and clean the steam wand. Fill a 600ml milk pitcher with 300ml cold water and run the steam wand through it after each milk frothing session to prevent milk residue buildup.

How do I know if my espresso machine boiler needs descaling?

If your shots are slower than usual, the machine takes longer to heat, or you hear unusual noises from the boiler, it may be due to scale buildup. Monthly draining and annual or biannual descaling (depending on water hardness) are recommended to prevent these issues.
